A black hairy tongue is caused by too much bacteria or yeast growth in the mouth: the bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
Temporary staining of your tongue will clear up once you stop using whatever product is causing the blackening of your tongue. Fungus or bacteria on your tongue that turn it black will also clear up with time if you practice improved oral hygiene.
